The surface speed for the same rpm jumps to 18,850 inches per minute which is 1,570 feet per minute. Notice that the diameter of the large roll is 6 times the diameter of the first roll and the surface speed is 6 times that of the first roll. We say that the surface speed varies di-rectly as the diameter if the rotation speed or rpm stays constant.
